Answer 1

输入这个css代码

.bmd-layout-header .navbar{
      position: fixed;
    right: 0;
    left: 0;
}
.bmd-layout-content {
    padding-top: 56px;
}

或

你可以把 material css .fixed-top class 放在 .navbar class 旁边然后把这个 css 这样你的布局不重叠以修复 header

.bmd-layout-content {
    padding-top: 56px;
}

Answer 2

你在html中这样添加class了吗？

Answer 3

您的标记全部不正确，已修复标记，css 的联结已更新。

您可以添加 sticky-top class 使元素粘在顶部。

请检查更新后的 jsfiddle Here

由于html太长，这里就不完整更新了，只贴一下header部分。

<header class="bmd-layout-header sticky-top">
        <div class="navbar bg-light bg-faded">
            <button class="navbar-toggler" type="button" data-toggle="drawer" data-target="#dw-s2">
                <span class="sr-only">Toggle drawer</span>
                <i class="material-icons">menu</i>
            </button>
            <a href="index.html" class="navbar-brand" style="padding-right: 27%;">aabbaaaa</a>

            <a href="profile.html" style="text-decoration: none; color: black;"><i class="far fa-user-circle pl-1"
                    style="padding:0;"></i></a>
            <a href="cart.html" style="color: inherit!important;"><i class="fas fa-shopping-cart pl-1"><sup><span
                            class="badge badge-info">0</span></sup></i></a>
        </div>
    </header>
